Examples of the implementation manners are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The implementation manners described below with reference to the accompanying drawings are exemplary only for explaining the present application and should not be construed as a limitation to the present application.

[0025] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present application.

[0026] With the development of science and technology, cooking appliances are becoming more and more diverse. Currently, most cooking appliances include heating elements. Correspondingly, the cooking process of cooking appliances mostly completes the cooking of food by controlling the heating of the heating elements. During the cooking process, due to the rise in temperature, the oil fume generated during the cooking process may adhere to the heating elements, causing oil stains on the surface of the heating elements, thereby affecting the heat transfer efficiency of the heating elements; in addition, the oil stains remaining on the heating elements for a long time will also make the cooking process of the cooking appliance unhygienic.

[0027] Therefore, in the related art, since the oil stains adhering to the heating elements included in the cooking appliances will affect the heat conduction of the heating elements and also make the cooking unhygienic, the cooking appliances have the problem of low cooking reliability.

[0028] In view of the above problems, through long-term research, the inventors have found and proposed a cooking appliance, a cleaning method and a device provided in an embodiment of the present application. By means of hot and cold flushing, the heating element is maintained, improving the reliability of the cooking appliance. Among them, the specific cleaning method will be described in detail in the subsequent embodiments.

[0029] Please refer to Figure 1 , which shows a schematic diagram of a cooking appliance provided in an embodiment of the present application. In the embodiment of the present application, the cooking appliance 100 may include a housing assembly 10, a frying barrel 20, a heating element 30, a spraying device 40, and a control device 50 (not shown in the figure).

[0030] Among them, the housing assembly 10 is provided with a receiving cavity, and the frying barrel 20 is movably arranged in the receiving cavity. The frying barrel 20 may include a bottom wall and a peripheral wall. The peripheral wall is circumferentially connected to the periphery of the bottom wall to jointly form a cooking cavity for receiving food. The heating element 30 is arranged in the housing assembly 10 for heating the cooking cavity. The spraying device 40 is arranged in the housing assembly 10 for spraying water on the heating element 30 when cleaning the heating element 30; the control device 50 is connected to the heating element 30 for controlling the heating parameters of the heating element 30 during the process of the spraying device 40 spraying water on the heating element 30, such as heating time, heating power, etc.

[0031] Among them, the cooking appliance 100 may have a cooking function. The cooking appliance 100 can generate hot air through the heating element 30, and then make the hot air circulate rapidly in a sealed space through a hot air convection system, thereby realizing the method of heating food. In the embodiment of the present application, the cooking appliance 100 may be an air fryer with a cooking function.

[0032] Among them, according to Figure 1 it can be seen that the housing assembly 10 plays a supporting role. The housing assembly 10 includes a bottom cover, side walls and a top plate. The bottom cover and the top plate are spaced apart in a specified direction. The specified direction refers to the direction perpendicular to the plane where the bottom cover is located. One side of the side wall is circumferentially connected to the periphery of the bottom cover, and the other side is circumferentially connected to the periphery of the top plate. The housing assembly 10 is provided with a receiving cavity for receiving the frying barrel 20. The side wall is formed with an opening for placing the frying barrel 20 in the receiving cavity.

[0033] In some embodiments, a control panel is provided on the outer surface of the side wall of the housing assembly 10 or on the surface of the top plate away from the bottom cover. The control panel includes one or more function controls, and the above function controls include but are not limited to a start control, a reservation control, a time setting control, a mode setting control, a food type setting control, etc.

[0034] The frying barrel 20 can be movably arranged in the accommodating cavity. When the frying barrel 20 is arranged in the accommodating cavity, a handle is provided on the surface of the frying barrel 20 exposed from the accommodating cavity for the user to grip. The frying barrel 20 includes a bottom wall and a peripheral wall, and the peripheral wall is connected around the periphery of the bottom wall to jointly form a cooking cavity for accommodating food.

[0035] The heating element 30 is used to realize the cooking function of the cooking appliance 100. Optionally, the heating element 30 can include a heating tube, a heating plate, etc., which are not limited herein. Exemplarily, the heating element 30 can include a heating tube with parameters of DC voltage 220V, 50Hz, and 1000W. In some embodiments, the heating element 30 is correspondingly arranged with the cooking cavity and is fixedly arranged in the housing assembly 10 through a fixing structure. The heating element 30 is used for heating to raise the temperature of the gas in the cooking cavity, and can also be used for heating during the cleaning process of the heating element 30 to soften the oil stains on the surface of the heating element 30.

[0036] The spraying device 40 is used to spray water on the heating element 30 to clean the heating element 30 when cleaning the heating element 30. Among them, the spraying device 40 is correspondingly arranged with the heating element 30 and is fixedly arranged in the housing assembly 10 through a fixing structure. It should be noted that the fixing structure for fixing the heating element 30 and the fixing structure for fixing the spraying device 40 can be the same or different.

[0037] The control device 50 is connected to the heating element 30 and is used to control the heating time of the heating element 30 during the process of the spraying device 40 spraying water on the heating element 30. Among them, the control device 50 can also be connected to the spraying device 40 and is used to control the time for the spraying device 40 to spray water on the heating element 30 during the cleaning process of the heating element 30.

[0038] In some embodiments, the control device 50 is further connected to the control panel on the housing assembly 10. When the control panel receives an operation signal for any one of the function controls, it generates a corresponding electrical signal and sends it to the control device 50, and the control device 50 controls the cooking appliance 100 based on this electrical signal. Optionally, the control device 50 is a Micro Controller Unit (MCU).

[0039] Please refer to again Figure 1, in some embodiments, the cooking appliance 100 may further include a hot air blower 101. The hot air blower 101 is disposed in the housing assembly 10 and on a side away from the cooking cavity relative to the heating element 30, and is configured to blow air to the heating element 30 when the heating element 30 is being cleaned. The hot air blower 101 is spaced apart from the heating element 30, and the hot air blower 101 is also fixedly disposed in the housing assembly 10 through a fixing structure. In some embodiments, the hot air blower 101 can also be used to cause the high-temperature gas generated by the heating of the heating element 30 to circulate convectively in the cooking cavity, thereby cooking the food. It should be noted that the fixing structure for fixing the heating element 30 and the fixing structure for fixing the hot air blower 101 may be the same or different.

[0040] When the cooking appliance 100 includes the hot air blower 101, the control device 50 is connected to the hot air blower 101 and is configured to control the operating parameters of the hot air blower 101, such as the rotation speed and rotation duration of the hot air blower 101. The hot air blower 101 may include a fan with parameters of DC220V, 50Hz, and 1000W.

[0041] Please refer to again Figure 1 , in some embodiments, the spraying device 40 may further include a water tank 401, a water pump 402, a water flow path 403, and a solenoid valve 404. The water pump 402 is configured to pump the water in the water tank 401 and spray the water along the water flow path 403 to the heating element 30 when the solenoid valve 404 is in an open state. Exemplarily, the parameters of the water pump 402 may be DC220V and 400mA; the parameters of the solenoid valve 404 may be DC12V and 200mA.

[0042] When the cooking appliance 100 includes the solenoid valve 404, the control device 50 can be connected to the solenoid valve 404 to control the operating state of the solenoid valve 404. For example, the control device 50 can send an electrical signal to the solenoid valve 404 to control the solenoid valve 404 to open.

[0043] Optionally, the spraying device 40 may further include one or more water spray nozzles. When the solenoid valve 404 is in an open state, the spraying device 40 can spray water to the heating element 30 from the one or more water spray nozzles.

[0044] In some embodiments, the number of solenoid valves included in the spraying device 10 may be one or more. Different solenoid valves can be used as the water spray switches for different water spray nozzles. Exemplarily, please refer to Figure 2, which shows a structural block diagram of a cooking appliance provided in an embodiment of the present application. Among them, the spraying device 40 may include solenoid valve A and solenoid valve B. Among them, solenoid valve A may serve as a waterway switch for opening the waterway in the direction of spraying the heating element 30, and solenoid valve B may serve as a waterway switch for opening the waterway in the direction of cooking and tenderizing by spraying the frying barrel 20.

[0045] In some embodiments, the spraying device 40 may further include a flow meter 405 (as Figure 2 shown), and the flow meter 405 is arranged on the water flow passage 403 and between the water pump 402 and the solenoid valve 404, and is used to detect the water flow in the water flow passage 403.

[0046] When the cooking appliance 100 includes the flow meter 405, the control device 50 may be connected to the flow meter 405, and is used to obtain the water flow in the water flow passage 403 detected by the flow meter 405, and determine whether to generate a water addition prompt message according to the water flow. For example, after the control device 50 obtains the water flow in the water flow passage 403 detected by the flow meter 405, it may compare the water flow with a preset water flow. If the water flow is less than the preset water flow, a water addition prompt message may be generated.

[0047] In some embodiments, a temperature detection device may be provided in the cooking cavity. The temperature detection device is connected to the control device 50, and is used to obtain the temperature information of the cooking cavity and report it to the control device. The control device 50 may adjust the heating power of the heating element 30 based on the obtained temperature information, so as to realize the temperature control of the cooking cavity and soften the oil stains on the heating element 30.

[0048] In some embodiments, the frying barrel 20 further includes a baking tray, and the baking tray is detachably arranged in the cooking cavity and is spaced from the bottom wall. The baking tray is provided with a food placement part, and the food placement part is provided with ventilation slots. When food is placed on the baking tray 220, the high-temperature gas generated by the heating of the heating element 30 can contact the bottom surface of the food (the surface where the food contacts the baking tray) through the ventilation slots, so that the food is heated more evenly.

[0049] In some embodiments, the food placement part is provided with a weighing device, which is used to obtain the weight of the food placed in the frying barrel 20 and report it to the control device 50. When the control device 50 determines that there is no food in the frying barrel 20, it may control the heating element 30 to heat and control the spraying device to spray water on the heating element 30 to clean the heating element 30.

[0050] In some embodiments, the control device 50 may execute the current cleaning process after receiving a cleaning instruction. The current cleaning process includes a hot cleaning stage and a cold cleaning stage. Among them, in the hot cleaning stage, when cleaning the heating element 30, the control device 50 may control the heating element 30 to generate heat and control the spraying device 40 to spray water on the heating element 30. Among them, in the hot cleaning stage, the control device 50 may obtain the temperature of the cooking cavity. If the temperature is greater than a preset temperature, the cold cleaning stage may be performed.

[0051] Among them, in the cold cleaning stage, the control device 50 may control the heating element 30 to stop generating heat and control the spraying device 40 to continue spraying water on the heating element 30. Further, the control device 50 may detect the spraying duration of the spraying device 40 spraying water on the heating element 30; and compare the spraying duration with a preset cleaning duration. If it is detected that the spraying duration of the spraying device 40 reaches the preset cleaning duration, the control device 50 may control the spraying device 40 to stop spraying water on the heating element 30, thereby maintaining the heating element 30 by means of hot and cold flushing, and improving the reliability of the cooking appliance 100.

[0052] Please refer to Figure 3 , Figure 3 FIG. shows a schematic flowchart of a cleaning method provided by an embodiment of the present application. The cleaning method maintains the heating element by means of hot and cold flushing, and improves the reliability of the cooking appliance. In a specific embodiment, the cleaning method may be applied to a cleaning device 200 as shown in Figure 11 and a cooking appliance 100 configured with the cleaning device 200 ( Figure 12 ). The following will take the cooking appliance as an example to illustrate the specific process of this embodiment. Of course, it can be understood that the cooking appliance to which this embodiment is applied may include an air fryer, an oven, a microwave oven, etc., which are not limited herein. The following will elaborate in detail on the Figure 3 flow shown in FIG. The cleaning method may specifically include the following steps:

[0053] Step S110: When cleaning the heating element, control the heating element to generate heat and control the spraying device to spray water on the heating element.

[0054] In some embodiments, a cooking appliance may include operating modes such as a cleaning mode, a cooking mode, a warming mode, a standby mode, etc. Among them, in the cleaning mode, the cooking appliance can clean the heating element included in the cooking appliance; in the cooking mode, the cooking appliance can cook the food placed in the cooking appliance; in the warming mode, the cooking appliance can keep the food placed in the cooking appliance warm; in the standby mode, each component included in the cooking appliance is in a standby state, and the cooking appliance can receive a control instruction input by the user and switch the operating mode of the cooking appliance based on the control instruction. Exemplarily, the cooking appliance can receive a first cleaning instruction input by the user in the standby mode and clean the heating element included in the cooking appliance in response to the first cleaning instruction.

[0055] As an implementable manner, the cooking appliance can receive a first cleaning instruction input by the user, wherein the first cleaning instruction may carry a preset cleaning duration. Correspondingly, when receiving the first cleaning instruction, the cooking appliance can determine that it is necessary to clean the heating element included in the cooking appliance. Further, the cooking appliance can parse the first cleaning instruction to obtain the preset cleaning duration carried by the first cleaning instruction and perform subsequent cleaning operations on the heating element based on the preset cleaning duration.

[0056] As another implementable manner, the preset cleaning duration for the cooking appliance to clean the heating element is fixed. The cooking appliance can receive a second cleaning instruction input by the user, wherein the second cleaning instruction does not carry a preset cleaning duration. Correspondingly, when receiving the second cleaning instruction, the cooking appliance can determine that it is necessary to clean the heating element included in the cooking appliance. Further, the cooking appliance can perform subsequent cleaning operations on the heating element based on the fixed preset cleaning duration.

[0057] Optionally, the preset cleaning duration can be set by the user independently or obtained through third-party experimental data. Exemplarily, the preset cleaning duration is 5 minutes and is set by the user independently.

[0058] In this embodiment, when cleaning the heating element, the cooking appliance can control the heating element to generate heat and can control the spraying device to spray water on the heating element. Exemplarily, please refer to again Figure 2, wherein when cleaning the heating element, the cooking appliance can control the solenoid valve A to open, that is, turn on the waterway switch in the direction of spraying the heating element, that is, control the spraying device to spray water on the heating element. The cooking appliance can also control the solenoid valve B to close, that is, close the waterway switch in the cooking and roasting direction of spraying the frying barrel, so as to ensure the water flow rate of spraying the heating element and improve the strength of spraying and flushing the heating element, improving the cleaning effect while saving water resources. It can be understood that while the cooking appliance controls the solenoid valve A to open and the solenoid valve B to close, it controls the heating element to generate heat, and can soften the oil stains attached to the heating element.

[0059] That is, in this embodiment, when cleaning the heating element, the cooking appliance can control the heating element to generate heat, and control the spraying device to spray water on the heating element, and then perform hot cleaning on the heating element to maintain the heating element and improve the reliability of the cooking appliance.

[0060] In some embodiments, the cooking appliance can obtain the temperature of the cooking cavity in real time during the process of controlling the heating element to generate heat. The cooking cavity may be provided with a temperature detection device, which can be connected to the control device and can be used to obtain the temperature information of the cooking cavity and report it to the control device, so that the control device determines the subsequent steps of cleaning the heating element according to the temperature information.

[0061] In some embodiments, a preset temperature may be preset in the cooking appliance. Further, after the cooking appliance obtains the temperature of the cooking cavity, it can compare the temperature with the preset temperature, and use the comparison result as the basis for judging whether to control the heating element to stop generating heat and control the spraying device to continue spraying water on the heating element. Exemplarily, if the temperature is greater than the preset temperature, the heating element is controlled to stop generating heat, and the spraying device is controlled to continue spraying water on the heating element.

[0062] As an implementable method, after the cooking appliance obtains the temperature of the cooking cavity, it can compare the temperature with the preset temperature. If the temperature is greater than the preset temperature, the cooking appliance can also obtain the duration during which the temperature of the cooking cavity is greater than the preset temperature. Further, the cooking appliance can compare the duration with a preset duration. If the duration is greater than the preset duration, the heating element can be controlled to stop generating heat, and the spraying device can be controlled to continue spraying water on the heating element.

[0063] The preset temperature can be set independently by the user or obtained through third-party experimental data. Exemplarily, the preset temperature obtained through third-party experimental data is 200 °C. The preset duration can be set independently by the user or obtained through third-party experimental data. Exemplarily, the preset duration obtained through third-party experimental data is 5 seconds.

[0064] Exemplarily, the preset temperature is 200°C and the preset duration is 5 seconds. After the cooking appliance obtains the temperature of the cooking cavity, if the temperature is greater than 200°C and the duration is greater than 5 seconds, the cooking appliance can control the heating element to stop heating and control the spraying device to continue spraying water on the heating element. Among them, if the temperature is less than or equal to 200°C, or the duration is not greater than 5 seconds, then control the heating element to keep heating and control the spraying device to keep spraying water on the heating element.

[0065] In this embodiment, when the temperature of the cooking cavity of the cooking appliance is greater than the preset temperature, the heating element can be cold-cleaned, and the oil stains attached to the heating element can be washed away by spraying water on the heating element; in addition, by stopping the heating element from heating and using the residual heat of the heating element for cleaning the heating element, the power consumption of cleaning the heating element is reduced. Therefore, this embodiment can clean the heating element by means of cold and hot cleaning, improving the reliability of the whole cooking appliance and enhancing the cooking performance of the cooking appliance.

[0066] In some embodiments, during the process of the cooking appliance controlling the spraying device to spray water, the spraying duration of the spraying device can be recorded. Correspondingly, after the cooking appliance obtains the spraying duration, the spraying duration can be compared with the preset cleaning duration, and the comparison result can be used as the judgment basis for determining whether to perform the operation of controlling the spraying device to stop spraying water on the heating element. Exemplarily, if it is detected that the spraying duration of the spraying device reaches the preset cleaning duration, then control the spraying device to stop spraying water on the heating element.

[0067] In some embodiments, the comparison result between the spraying duration and the preset cleaning duration can also be used as the judgment basis for determining whether to switch the working mode of the cooking appliance from the cleaning mode to the standby mode. Exemplarily, if it is detected that the spraying duration of the spraying device reaches the preset cleaning duration, then switch the working mode of the cooking appliance from the cleaning mode to the standby mode. It can be understood that when the cooking appliance is in the standby mode, the heating element included in the cooking appliance stops heating and the spraying device stops spraying water.

[0068] The cleaning method provided by an embodiment of the present application, when cleaning the heating element, controls the heating element to heat and controls the spraying device to spray water on the heating element, thereby maintaining the heating element by means of cold and hot flushing, and improving the reliability of the cooking appliance.

[0069] Please refer to Figure 4 , Figure 4 which shows a schematic flowchart of the cleaning method provided by an embodiment of the present application. This method is applied to the above-mentioned cooking appliance, and the following will elaborate in detail on the Figure 4 shown process. The cleaning method can specifically include the following steps:

[0070] Step S210: When cleaning the heating element, control the heating element to generate heat and control the spraying device to spray water onto the heating element.

[0071] For the specific description of step S210, please refer to the specific description of step S110 above, and details will not be elaborated here.

[0072] Step S220: Obtain the temperature of the cooking cavity.

[0073] In some embodiments, the cooking appliance can obtain the temperature of the cooking cavity in real time during the process of controlling the heating element to generate heat. Among them, a temperature detection device can be provided in the cooking cavity. The temperature detection device can be connected to the control device and can be used to obtain the temperature information of the cooking cavity and report it to the control device, so that the control device can determine the subsequent steps for cleaning the heating element according to the temperature information.

[0074] Step S230: If the temperature is greater than the preset temperature, control the heating element to stop generating heat, and control the spraying device to continue spraying water onto the heating element periodically at a preset time interval within a preset spraying duration.

[0075] In some embodiments, after the cooking appliance obtains the temperature of the cooking cavity, it can compare the temperature with the preset temperature, and use the comparison result as the basis for determining whether to control the heating element to stop generating heat, and control the spraying device to continue spraying water onto the heating element periodically at a preset time interval within a preset spraying duration. Exemplarily, if the temperature is greater than the preset temperature, control the heating element to stop generating heat, and control the spraying device to continue spraying water onto the heating element periodically at a preset time interval within a preset spraying duration.

[0076] Among them, the preset spraying duration can be pre-set in the cooking appliance. The preset spraying duration is less than the preset cleaning duration. The preset spraying duration can be one and a half minutes, two minutes, etc., and is not limited here. Among them, the preset time interval can be pre-set in the cooking appliance. The preset time interval is less than the preset spraying duration and can be 5 seconds, 6 seconds, etc., and is not limited here. Among them, the time for spraying water onto the heating element periodically at a preset time interval within the preset spraying duration can be 10 seconds, 11 seconds, etc., and is not limited here.

[0077] Exemplarily, if the temperature of the cooking cavity is greater than the preset temperature, the cooking appliance can control the heating element to stop generating heat, and can also control the water pump included in the spraying device to work at full speed to pump water from the water tank, and continue to spray water onto the heating element cyclically at a spraying interval of turning on for 10 seconds and turning off for 5 seconds within 2 minutes to wash the heating element.

[0078] In some embodiments, if the water spraying duration of the spraying device is greater than the preset spraying duration and less than the preset cleaning duration, step S210 can be returned to for execution until it is detected that the water spraying duration of the spraying device reaches the preset cleaning duration, and then step S240 is executed.

[0079] Among them, the water spraying duration of the spraying device can include the duration of spraying water on the heating element during the heating stage of the heating element, and can also include the duration of the spraying device intermittently spraying the heating element after the heating element stops heating. Among them, if the water spraying duration of the spraying device is greater than the preset spraying duration and less than the preset cleaning duration, it can be understood that the time for cleaning the heating element has not reached the preset cleaning duration, and the residual heat of one-time heating of the heating element is used to complete one-time cold and hot flushing of the heating element. Further, the cooking appliance can return to step S210, and then perform cyclic cold and hot cleaning on the heating element, improving the thoroughness of cleaning the heating element and the reliability of cooking of the cooking appliance.

[0080] Step S240: If it is detected that the water spraying duration of the spraying device reaches the preset cleaning duration, control the spraying device to stop spraying water on the heating element.

[0081] In some embodiments, during the process of the cooking appliance controlling the spraying device to spray water, the water spraying duration of the spraying device can be recorded. Correspondingly, after the cooking appliance obtains the water spraying duration, it can compare the water spraying duration with the preset cleaning duration, and use the comparison result as the judgment basis for determining whether to perform the operation of controlling the spraying device to stop spraying water on the heating element. Exemplarily, if it is detected that the water spraying duration of the spraying device reaches the preset cleaning duration, control the spraying device to stop spraying water on the heating element.

[0082] The cleaning method provided by an embodiment of the present application, compared with Figure 3 the shown cleaning method, this embodiment can also control the heating element to stop heating if the temperature of the cooking cavity is greater than the preset temperature, and control the spraying device to continue spraying water on the heating element periodically at preset time intervals within the preset spraying duration. By intermittently spraying water to clean the heating element while performing cold and hot cleaning on the heating element, the cleaning water is saved, and while maintaining the heating element, the reliability of the cooking appliance is improved.

[0083] Please refer to Figure 5 , Figure 5 which shows a schematic flowchart of the cleaning method provided by an embodiment of the present application. This method is applied to the above-mentioned cooking appliance, and the following will elaborate in detail on Figure 5 the shown process. The cleaning method can specifically include the following steps:

[0084] Step S310: If it is detected that the water volume in the water tank included in the spraying device is greater than the water volume threshold and there is no food in the frying barrel, then control the heating element to generate heat, and control the spraying device to spray water on the heating element.

[0085] In some embodiments, the cooking appliance can record and accumulate the cooking times each time the cooking appliance finishes cooking. Further, the cooking appliance can determine whether it is necessary to clean the heating element based on the record and accumulation of the cooking times.

[0086] As an implementable manner, when the cooking appliance determines that it is necessary to perform an operation of cleaning the heating element based on the record and accumulation of the cooking times, it can further detect the water volume in the water tank included in the cooking appliance and detect whether there is food in the frying barrel; if it is detected that the water volume in the water tank included in the spraying device is greater than the water volume threshold and there is no food in the frying barrel, then the heating element can be controlled to generate heat, and the spraying device can be controlled to spray water on the heating element.

[0087] Please refer to Figure 6 , in some embodiments, step S311 may further be included before step S310.

[0088] Step S311: If it is detected that the number of times the cooking appliance has finished cooking reaches a preset cooking number, then generate a second prompt message, where the second prompt message is used to prompt to clean the cooking appliance.

[0089] In some embodiments, the cooking appliance can record and accumulate each cooking. If the cooking appliance detects that the number of times the cooking appliance has finished cooking reaches a preset cooking number, then a second prompt message can be generated.

[0090] Among them, the preset cooking number can be preset in the cooking appliance, can be set by the user independently, or can be obtained through third-party experimental data. Exemplarily, the preset cooking number is set by the user independently to 20 times. Further, if the cooking appliance detects that the number of times the cooking appliance has finished cooking reaches 20 times, then a second prompt message can be generated.

[0091] Among them, the second prompt message can include an audio prompt message, an indicator light prompt message, a text display prompt message, etc., which are not limited herein. Among them, the second prompt message can be used to prompt that the cooking appliance needs maintenance, or can be used to prompt that the heating element included in the cooking appliance needs to be cleaned.

[0092] As an implementable manner, the user can fill the water tank included in the cooking appliance with water based on the second prompt information, and leave the fryer of the cooking appliance empty. Further, when the cooking appliance detects that the water volume in the water tank included in the spraying device is greater than the water volume threshold and there is no food in the frying barrel, it can control the heating element to generate heat and control the spraying device to spray water on the heating element.

[0093] As another implementable manner, the user can input a cleaning instruction based on the second prompt information. Further, the cooking appliance can perform an operation of cleaning the heating element by hot and cold water in response to the cleaning instruction input by the user. Among them, the way for the user to input the cleaning instruction can be to touch the cleaning function button included in the cooking appliance, or to input the cleaning instruction by voice, or to input the cleaning instruction from an associated electronic device, and the associated electronic device controls the cooking appliance to clean the heating element.

[0094] In some embodiments, after the cooking appliance finishes cleaning the heating element, it can clear the cooking times recorded and accumulated in the cooking appliance, and record and accumulate the cooking times of the cooking appliance again, so as to give a cleaning reminder regularly, improve the reliability of the cooking appliance, and ensure the cooking performance of the cooking appliance.

[0095] Further, if the cooking appliance detects that the water volume in the water tank included in the spraying device is greater than the water volume threshold and there is no food in the frying barrel, it can control the heating element to generate heat and control the spraying device to spray water on the heating element. Among them, the water volume in the water tank being greater than the water volume threshold can be used as a condition to ensure the effect of spraying and cleaning the heating tube. When there is no food in the frying barrel, cleaning the heating element ensures the reliability of the cooking appliance and improves the user experience.

[0096] Among them, a water volume threshold can be preset in the cooking appliance. It can be understood that when the water volume in the water tank is sufficient and there is no food in the frying barrel, cleaning the heating element improves the rationality of cleaning the heating element, improves the cleaning effect of the heating element, and improves the cooking performance of the cooking appliance.

[0097] Please refer to Figure 7 , in some embodiments, step S312 may further be included before step S310.

[0098] Step S312: If it is detected that the duration for which the heating element has not been cleaned meets a preset duration, generate a third prompt information, where the third prompt information is used to prompt to clean the cooking appliance.

[0099] Optionally, the cooking appliance can record the duration for which the heating element has not been cleaned; the cooking appliance can also be connected to an associated electronic device or the cloud. Further, the associated electronic device or the cloud can record the duration for which the heating element included in the cooking appliance has not been cleaned.

[0100] In some embodiments, the cooking appliance can obtain the duration for which the heating element has not been cleaned, and compare this duration with a preset duration. If it is detected that the duration for which the heating element has not been cleaned meets the preset duration, a third prompt message can be generated. The third prompt message can be used to prompt for cleaning the cooking appliance.

[0101] The preset duration can be pre-set in the cooking appliance, can be set by the user independently, or can be obtained from third-party experimental data. Exemplarily, the preset duration is set by the user independently to 20 days. Further, if it is detected that the duration for which the heating element has not been cleaned reaches 20 days, a third prompt message can be generated.

[0102] The third prompt message can include an audio prompt message, an indicator light prompt message, a text display prompt message, etc., which are not limited herein. The third prompt message can be used to prompt that the cooking appliance needs maintenance and can be used to prompt that the heating element included in the cooking appliance needs to be cleaned.

[0103] As an implementable manner, the cooking appliance is connected to an associated electronic device, and the electronic device includes an application program for recording the number of days the cooking appliance has not been cleaned. When the application program detects that the number of days the cooking appliance has not been cleaned meets the preset number of days, the application program can send a prompt identifier to the cooking appliance. Further, the cooking appliance can generate a third prompt message based on the prompt identifier. Exemplarily, the cooking appliance can control the cleaning function light included in the cooking appliance to turn on, the buzzer to work, the display screen to work, etc. based on the prompt identifier.

[0104] As an implementable manner, the user can fill the water tank included in the cooking appliance with water based on the third prompt message and leave the fryer of the cooking appliance empty. Further, the cooking appliance can control the heating element to heat up and control the spraying device to spray water on the heating element when it detects that the water volume in the water tank included in the spraying device is greater than the water volume threshold and there is no food in the frying barrel.

[0105] As another implementable manner, the user can input a cleaning instruction based on the third prompt message. Further, the cooking appliance can perform an operation of performing hot and cold cleaning on the heating element in response to the cleaning instruction input by the user.

[0106] In some embodiments, after the cooking appliance finishes cleaning the heating element, it can clear the recorded duration for which the heating element has not been cleaned and record the duration for which the heating element has not been cleaned again to perform cleaning reminders regularly, improve the reliability of the cooking appliance, and ensure the cooking performance of the cooking appliance.

[0107] Step S320: Obtain the temperature of the cooking cavity.

[0108] Among them, for the specific description of step S320, please refer to the specific description of step S220 above, and it will not be elaborated here in detail.

[0109] Step S330: If the temperature is greater than the preset temperature, control the heating element to stop heating, and control the spraying device to continue spraying water on the heating element.

[0110] In some embodiments, after the cooking appliance obtains the temperature of the cooking cavity, it can compare this temperature with the preset temperature. If this temperature is greater than the preset temperature, it can obtain the water flow rate detected by the flow meter included in the spraying device; if the water flow rate is less than the preset water flow rate, a first prompt message is generated, where the first prompt message is used to prompt adding water to the water tank included in the spraying device.

[0111] In this embodiment, when the cooking appliance determines that the temperature of the cooking cavity is greater than the preset temperature, it can control the heating element to stop heating and control the spraying device to continue spraying water on the heating element, so as to utilize the residual temperature of the heating element and the impact force of the sprayed water to clean the heating element. Among them, considering that the impact force of the sprayed water is related to the water flow rate, in this embodiment, the water flow rate detected by the flow meter included in the spraying device can be obtained. If the water flow rate is less than the preset water flow rate, a first prompt message can be generated, so that the user can add water to the water tank based on this first prompt message to ensure the impact force of the sprayed water, thereby improving the thoroughness of cleaning the heating element. Among them, the preset water flow rate can be preset in the cooking appliance.

[0112] Among them, the water flow meter can detect the water flow rate, that is, it can detect the water flow volume. Further, after the cooking appliance obtains this water flow volume, it can compare this water flow volume with the preset water flow volume, and use this comparison result as the judgment basis for determining whether to generate the first prompt message for prompting adding water. Exemplarily, if the water flow volume is less than the preset water flow volume, it can be determined that the water flow rate is low, and it can also be determined that a first prompt message for prompting adding water needs to be generated.

[0113] Step S340: If it is detected that the water spraying duration of the spraying device reaches the preset cleaning duration, control the spraying device to stop spraying water on the heating element.

[0114] The cleaning method provided by an embodiment of the present application, compared with Figure 3 the shown cleaning method, in this embodiment, if it is detected that the water volume in the water tank included in the spraying device is greater than the water volume threshold and there is no food in the frying bucket, control the heating element to heat, and control the spraying device to spray water on the heating element, thereby ensuring that the conditions for cleaning the heating element are reasonable. By regularly performing cold and hot cleaning on the heating element, the performance of the heating element is ensured, and the reliability of the cooking appliance is improved.

[0115] Please refer to Figure 8 , Figure 8The flowchart of the cleaning method provided by an embodiment of the present application is shown. This method is applied to the above-mentioned cooking appliance. The following will elaborate on the Figure 8 process shown in detail. The cleaning method may specifically include the following steps:

[0116] Step S410: When cleaning the heating element, control the heating element to generate heat, and control the spraying device to spray water on the heating element.

[0117] For the specific description of step S410, please refer to the specific description of step S110 in the previous text, and details will not be repeated here.

[0118] Step S420: Obtain the temperature of the cooking cavity.

[0119] For the specific description of step S420, please refer to the specific description of step S220 in the previous text, and details will not be repeated here.

[0120] Step S430: If the temperature is greater than the preset temperature, control the heating element to stop generating heat, control the hot air blower included in the cooking appliance to blow air on the heating element, and control the spraying device to continue spraying water on the heating element.

[0121] In some embodiments, after the cooking appliance determines that the temperature of the cooking cavity is greater than the preset temperature, it can control the heating element to stop generating heat, and control the hot air blower included in the cooking appliance to blow air on the heating element, thereby using the wind force of the hot air blower to improve the efficiency of cleaning the heating element. Further, the cooking appliance can also control the spraying device to continue spraying water on the heating element, thereby improving the cleaning effect on the heating element.

[0122] As an implementable manner, the cooking appliance can, during the process of cleaning the heating element, while controlling the heating element to generate heat and the spraying device to spray water on the heating element, control the hot air blower to blow air based on a first power. Further, after the cooking appliance determines that the temperature of the cooking cavity is greater than the preset temperature, it can control the heating element to stop generating heat, and control the hot air blower included in the cooking appliance to blow air on the heating element based on a second power, where the second power is greater than the first power, so as to avoid the rapid loss of heat generated during the heating stage of the heating element, improve the power of the heating element to generate heat, and improve the cleaning effect on the heating element based on a stronger wind force during the stage when the heating element stops generating heat.

[0123] As another implementable way, during the process of cleaning the heating element, the cooking appliance can control the heating element to generate heat and the spraying device to spray water on the heating element while controlling the hot air blower not to blow air. Further, after the cooking appliance determines that the temperature in the cooking cavity is greater than the preset temperature, it can control the heating element to stop generating heat and control the hot air blower included in the cooking appliance to blow air, so as to avoid the rapid loss of heat generated during the heating stage of the heating element, improve the power of the heating element to generate heat, and improve the cleaning effect of the heating element based on stronger wind power during the stage when the heating element stops generating heat.

[0124] Step S440: If it is detected that the water spraying duration of the spraying device reaches the preset cleaning duration, control the spraying device to stop spraying water on the heating element.

[0125] In some embodiments, if the cooking appliance detects that the water spraying duration of the spraying device reaches the preset cleaning duration, it can control the spraying device to stop spraying water on the heating element, which can be understood as that if the cooking appliance detects that the cleaning time of the heating element reaches the set preset cleaning duration, it returns to the standby mode.

[0126] Exemplarily, please refer to Figure 2 、 Figure 9 and Figure 10 , Figure 9 which shows the flowchart of the cleaning method provided by an embodiment of the present application. Figure 10 which shows the flowchart of the cleaning method provided by an embodiment of the present application. Among them, the cooking appliance can record the number of cooking completions, as shown in Figure 8 ; the cooking appliance can also record the number of days when the cooking appliance has not been cleaned through the application program, as shown in Figure 9 . Optionally, if the cooking appliance detects that the number of cooking completions reaches the preset number of cooking times, as shown in Figure 8 ; or if the application program detects that the number of days when the cooking appliance has not been cleaned reaches the preset number of days, as shown in Figure 9 , it can control the cleaning lamp included in the cooking appliance to light up to prompt the start of cleaning, or it can also send a prompt flag to the cooking appliance based on the application program to control the cleaning lamp included in the cooking appliance to light up to prompt the user to start cleaning. Further, the user can fill the water tank included in the cooking appliance with water based on the prompt, leave the frying bucket empty, and press the cleaning function button of the cooking appliance to start cleaning.

[0127] Further, when cleaning the heating element, the solenoid valve A can be controlled to open, the solenoid valve B can be controlled to close, the heating element can be controlled to generate heat, and the hot air blower can be controlled not to blow air. Thus, the spraying device sprays water on the heating element. Among them, it can be understood that during the process of the heating element generating heat, the oil stains on the surface of the heating element can be softened, and in addition, based on the spraying device spraying water on the heating element, the oil stains can flow away from the surface of the heating element along with the water flow, thereby performing thermal cleaning on the heating element.

[0128] Furthermore, the cooking appliance can obtain the temperature of the cooking cavity in real time, compare this temperature with a preset temperature (such as 200 °C). If the temperature of the cooking cavity is greater than 200 °C and lasts for more than 5 seconds, the heating element can be controlled to stop heating, and the hot air blower can be controlled to rotate to clean the oil stain on the heating element based on the wind force.

[0129] Furthermore, the cooking appliance can control the water pump to work at full speed, and control the spraying device to perform cyclic intermittent spraying on the heating element in the way of spraying for 10 seconds and stopping for 5 seconds. At the same time, the water flow rate of the water flow path can be detected based on the flow meter. Among them, if the time of cyclic spraying on the heating element is less than the preset spraying duration (such as 2 minutes), the heating element will continue to be sprayed cyclically and intermittently; if the time of cyclic intermittent spraying on the heating element is greater than or equal to 2 minutes, the control solenoid valve A will be opened, solenoid valve B will be closed, the heating element will heat up, and the hot air blower will be controlled not to blow air, and then the subsequent steps will be carried out to perform cold cleaning on the heating element, improving the reliability of the cooking appliance.

[0130] Among them, the cooking appliance can compare the detected water flow rate with the preset water flow rate, and when the water flow rate is less than the preset water flow rate, a first prompt message for prompting to add water to the water tank included in the spraying device will be generated to ensure the effect of cold cleaning.

[0131] It can be understood that during the process of the water pump working at full speed, the spraying intensity of the spraying device is relatively large. In order to ensure the performance of the heating element, in this embodiment, by means of intermittent spraying, during the process of cleaning the heating element, the heating element is prevented from being damaged.

[0132] Furthermore, if the spraying duration of the spraying device is detected, that is, the spraying duration during the heating stage of the heating element and the time of cyclic spraying on the heating element during the stage when the heating element stops heating, reaches the preset cleaning duration, the cooking appliance will be controlled to return to the standby state. That is, if the countdown of the preset cleaning duration is 0, the cooking appliance will be controlled to return to the standby state. Optionally, the cooking appliance can display the preset cleaning duration and can also display the cleaning countdown.

[0133] It can be understood that in this embodiment, by accumulating the usage times of the cooking appliance or by accumulating the duration when the cooking appliance has not been cleaned, the heating element is reminded to be cleaned regularly, improving the reliability of the whole cooking appliance and enhancing the performance of the menu of the cooking appliance.

[0134] The cleaning method provided by an embodiment of the present application, compared with Figure 3 the cleaning method shown, in this embodiment, if the temperature is greater than the preset temperature, the hot air blower included in the cooking appliance can be controlled to blow air towards the heating element. Furthermore, while improving the cleaning effect of the heating element by blowing air towards the heating element through the hair dryer, the heating element is maintained by means of cold and hot flushing, improving the reliability of the cooking appliance.
